Boom profile intelligent control system for boom sprayer and control method of boom profile intelligent control system

Abstract

The invention discloses a boom profile intelligent control system for boom sprayer and a control method of boom profile intelligent control system. The control system is mounted between a boom inner arm and a boom outer arm. A transmission rack is slidably mounted at the tail end of the boom inner arm. A sliding guiding mechanism and a hydraulic driving mechanism are arranged between the transmission rack and the boom inner arm. A transmission gear engaged with the transmission rack is fixedly mounted at the head end of the boom outer arm. A non-contact range sensor is fixedly mounted at the tail end of the boom outer arm. An ECU controller is connected with the signal output end of the non-contact range sensor and connected with the hydraulic driving mechanism through a hydraulic controlsystem. The distance between the boom profile intelligent control system and the ground is detected dynamically in real time through the non-contact range sensor, the extension length or retraction length of a driving oil cylinder piston rod is controlled by the intelligent control system in time, the effect that the distance between the boom outer arm and the ground is kept in a fixed value all the time is ensured, the spraying operation quality of the sprayer is improved, and the situation that a boom is damaged due to the fact that the boom makes contact with the uneven ground is avoided.

Description

technical field [0001] The invention belongs to the technical field of boom sprayers, and in particular relates to a spray boom profiling intelligent control system for a boom sprayer and a control method thereof. Background technique [0002] Due to the design of the boom structure or the small width of the boom, most of the existing boom sprayers in China do not have a boom profiling intelligent control system, and some boom sprayers rely on manual operation for the boom profiling control It is realized by controlling the position of the piston rod of the hydraulic cylinder with the handle or button of the hydraulic valve. Manual adjustment makes the distance from the spray boom to the ground inaccurate and unstable, and cannot be adjusted dynamically and quickly according to the fluctuations of the ground terrain, thus affecting the spraying quality of the sprayer; if the ground has large fluctuations, the spray boom cannot be adjusted quickly The distance from the groun...

[0002] Due to the design of the boom structure or the small width of the boom, most of the existing boom sprayers in China do not have a boom profiling intelligent control system, and some boom sprayers rely on manual operation for the boom profiling control The hydraulic valve handle or button is used to control the position of the hydraulic cylinder piston rod.

Manual adjustment makes the distance from the spray boom to the ground inaccurate and unstable, and cannot be adjusted dynamically and quickly according to the fluctuations of the ground terrain, thus affecting the spraying quality of the sprayer; if the ground has large fluctuations, the spray boom cannot be adjusted quickly The distance from the ground, which may cause the boom to contact the undulating ground and damage the boom
